Nano urea is a potential component of 4 R nutrient stewardship as it promotes precision and sustainable agriculture. It promotes clean and green technology as its industrial production is neither energy intensive nor resource consuming. Nano Urea confirms to Department of Biotechnology (DBT), Govt. of India guidelines for evaluation of Nano Agri-input products (NAIPs). These guidelines are harmonised as per approved international norms & OECD protocols. Nano Urea has been declared safe for the user and the environment as per tests conducted by NABL accredited and GLP certified laboratories. Nano Urea, therefore, stands as a promising, sustainable, and environmentally friendly solution to conventional bulk nitrogenous fertilizers like Urea.
